Comparison of Carotid Peak Systolic Velocity Variation With Aortic Peak Systolic Velocity Variation in Pediatric Non-Cardiac Surgery

Post Graduate Institute of Medical Education and Research, Chandigarh52 enrolled

Overview

The purpose of this study is to evaluate whether carotid Doppler peak systolic velocity can be an easy to measure possible surrogate for echocardiographic measurement of aortic peak systolic velocity variation which is an index of fluid responsiveness in mechanically ventilated children intra-operatively.

Study Type

OBSERVATIONAL

Enrollment

Conditions

Anesthesia, General Anesthesia, Endotracheal Mechanical Ventilation Fluid Responsiveness

Interventions

Measurement of aortic and carotid Doppler peak systolic velocity variation

Aortic peak systolic velocity variation to be measured by echocardiography from apical five chamber and suprasternal windows alongwith carotid peak systolic velocity variation by Doppler ultrasound simultaneously at intermittent time points intermittently.
